Engineering aspects of stents design and their translation into clinical practice

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Biomaterials Science

Background:

• Coronary stenting is a cornerstone of percutaneous revascularization, widely adopted due to proven efficacy over balloon angioplasty.
• Clinical trials demonstrated stenting's superiority in reducing restenosis and repeat interventions for specific lesion types.
• The market has seen rapid expansion with numerous bare metal and drug-eluting stent designs.

Purpose of the Study:

• To review critical stent design components influencing arterial wall biological response and clinical outcomes.
• To explore emerging stent platforms, particularly biodegradable stents, for enhanced vascular healing.
• To provide insights into the evolution and future directions of coronary stent technology.

Main Methods:

• Literature review of key clinical trials and technological advancements in coronary stenting.
• Analysis of stent design elements and their correlation with biological interactions.
• Discussion of novel stent materials and platforms, including biodegradable options.

Main Results:

• Stenting significantly reduces angiographic restenosis and the need for reintervention compared to balloon angioplasty.
• Various stent designs and materials elicit different biological responses from the arterial wall.
• Biodegradable stents represent a next-generation approach aiming for physiological integration and accelerated healing.

Conclusions:

• Stent design is crucial for optimizing biological response and clinical outcomes in coronary revascularization.
• Advancements in stent technology, including drug-eluting and biodegradable options, continue to improve patient care.
• Biodegradable stents hold potential for a more physiological approach, minimizing long-term complications and enhancing vessel recovery.
